<ul>The <b>Define Drawing Modification Time</b> function provides information
to WHIP! data reading applications about when the WHIP! data was last modified.</ul>

<ul><i>Time&nbsp;&nbsp;</i> The number of seconds elapsed since midnight
(00:00:00), January 1, 1970, coordinated universal time (GMT)
<p><i>Desc</i>&nbsp;&nbsp; Any humanly readable description of the time
when the file was last modified
<p><i>GUID</i>&nbsp;&nbsp; A globally unique identifier (GUID) represented
by an alpha-numeric description generated to capture the modification time
of the WHIP! data. When WHIP! data is initially created, the
creation and modification GUIDs match.</ul>
<font face="Arial Black"><font size=-1>Details</font></font>
<ul>Some WHIP! data reading applications may need to "know" when the
WHIP! data was last changed. The WHIP! data generating application can indicate 
this with the Modified opcode:
<ul><font face="Courier New"><font size=-1>(Created 820497600 'January
1, 1996' C0176e40-dc10-11d0-bb09)</font></font></ul>
</ul>
<font face="Arial Black"><font size=-1>Notes</font></font>
<ul>WHIP! data reading applications should not expect to be able to parse the
<i>Desc</i>
argument, though it could be shown to a user.
<p>WHIP! data should contain at most one occurrence of the modification
time opcode, which by convention should be nested inside a <b><a href="DefDwgInfoBlk.html">Define
Drawing Information Block</a></b> opcode.</ul>
<font face="Arial Black"><font size=-1>Default</font></font>
<ul>By default no drawing modification time is defined, which is equivalent
to
<ul><font face="Courier New"><font size=-1>(Modified 0 unknown unknown)</font></font></ul>
</ul>
